Specification forming part of Letters Patent No."l07,639, dated September 20, 1870.

To all whom, it 777,051/ concern: I

Be it known that we, JAMHs TRANTHR J osHPHKINsHY, and JOHN M. CARR, all of Cincinnati, Hamilton county, Ohio, have in.

` vented a new and useful Rotary Power-Plow,

of which the following is a specication.

Our device, in its `preferred form, consists, essentially, of a gang 4or series of shares or plows, to which are imparted a continuous rotary` and an intermittent vertical motion,

accompanying a continuous" advance of the revolving gang of plows along the surface of the field in the act of plowing.

" In the drawings, Figure l is a longitudinal section of a machine embodying` our invention. Fig. 2 is a transverse section on the line x zr. Fig. 3 lis a perspective view of the operative devices (gang of plows) detached.

p Fig. 4 is a diagram showinga modification of our invention. Figs. 5 and 6 are ,respect` ively a`,perspective View and a vertical section of a modification of our plow for cutting sod.

A represents a frame mountedupon three groundwheels, B C C,of whichl the'two rear wheels, C C', arermly secured to a common axle, D, carrying a` bevel-wheel, E, which gearswith a pinion, vF, upon a vertical shaft, G, whose spur-wheelII gears with a similar wheel, I, upon a second verticalfshaft, J, which shaft has` a disk or collar, K,-,having square or other non-circular perforations 7c, forthe stems or sheths L of, a series of shares orplows proper, M. In a line with the perforations lc the wheel I has other penforations, t', for saidstems towork up and do wnin., I

Aflixed to the frame, and encirclingthe front half ofthe collar K,is an incline or iixed cam, N. I I

Journaled to the stem of each plow is a roller, O, which, revolving during one-half of its circuit on the collar. K, maintains its respective plow at a given depth for that portion of its rotation, whence, passing onto and ascending `the cam N, the roller operates to unearththe plow, and to hold it out of the groundduring its passage around the other half of its circuit.

In order to enable the husbandman to set the plows to penetrate any depth desired, the

stem of each plow has a series of sockets, P, for the stud-shaft O of its roller.

I The shaft J ,with its perforated wheels or collars I and K, we call the revolving head,77 I .I `K.

The eective capacity of the machine may be increased, and at the same time side draft prevented, by the introduction of a second series or` rotary gang, revolving in the opposite direction to the first, as in Fig. 4. y

The groundwheels C C may, if desired, be so connected by ratchets to their axles as to rotate the latter in a forward motion only of the carriage.

For the removal and overturning of the surface-sod we employa plow or share, M-sucl1 as represented in Figs. 5 and 6-the vertical adjustment of the said plow being such as to but slightly penetrate the ground in the man- -ner required in sod-plowing.

The represented oval or convex contour and described motion of the plows7 cutting-edges enables them to act with a draw cut or curvling action upon the ground, and to surmount rocks or other immovable obstructlons, so `as nig. A.)

-We 4claim as new and of our invention- 1Ql The revolving head or heads I J K, armed with the series of movable plows or shares M M', adapted to operate upon the soil in the manner set forth.

2. The described arrangement of one or more series of plows, M or lVI, rotating head I J K, and fixed cam N, whereby the said plows are subjected, duringthe advance of the machine, to a continuous rotation, partly in and partly out of the ground.

3. In the described combination with the elements of the clause next preceding, the described arrangement of adjustable roller O. whereby the penetration of the plow is controlled.

In testimony of which invention we hereun-
